ANSWER 0001:
The diagram below shows contacting the forehead, the top
of the head, and an overhead view of the top of the head.
The overhead view symbol shows the circle for the top
of the head, and the dark lines on each side are the overhead
view of the shoulders.

You will find these symbols on key
"7" and "9" on the SignWriter keyboard.

EXAMPLES 0001:Some signs that relate
to the top of the head:

Sign for HAT in ASL

Sign for LION in ASL

QUESTION
0002:
How do I write curved fingers for letters like 'f', w',
instead of straight fingers as in ASL? There were several
other signs that I could not figure out how to write,
so I basically drew them on paper, but I need to be able
to enter them into the computer eventually.
